Be it known that I, J FRANK Aa'oass,`

a citizen of the United States, residing at the city of St. Louis, State of Missouri,. have invented certain new and useful Improvements in Pum Motors, of which the l ollowing is a s )eci cation, reference being had therein to t e accompanying drawings. y

This invention reliites to gas machines in which air and the vapors of hydrocarbon oil are combined in a earbiireter or mixer ras possessing great heating qualities and liigh illuminating power.

T he object of the present invention is to provide a motor that is intended to be used to operate a pump for forcing hydrocarbon oil to the aforesaid carbureter, and that is particularly adapted to be used in conjunction with a pump which supplies the carbureter with air.

In the accom anying drawin part of this specification, in whi like num bers of reference denote like arts wherever they occur, Figure 1 is an en eleviition of a gas machine with the motor in conjunction forming therewith; Fig. 2 is a top plan view, on an enlarged scale, showin the Vmotor in connection with a rotary air pump; and Fig. 3 is a sectional .view on the line 3-3, Fi". 2.

'l`he air pump 1, which is preferably ofthe rotary ty e, forces the air through pipe 2- to the car ureter 3, the internal construction of said ciirbureter being similar to that of the one disclosed in my United States Let teislatent, No. 876,678, granted January A rope 4 is wound on a drum 5 that is loosely mounted on shaft 6 of said air i 14, laos.

pump,l and passes over a slicave 7 fastened to a ceiling 8 or other support. Said rope passes over a pair of pulleys t), one of said pulleys bein f secured to said ceiling and the other one o said pulleys being attached to a weight 10, which holds said rope in tension and causes drum 5 to rotate in one direction. A bracket 11 is secured to one end of pump 1 and is arranged to form a bearing for i drain 5. The outer end of drum 5 projects 1 from said bracket to allow a crank handle (not shown in the drawin s) to be attached thereto for the purpose o rotating same in tlie opposite direction in order to rewind rope 4 on drum after weight 10 pulls said rope to such extent that same is nearlv unwound from said drum. u

Aratchet 12 is rigidly mounted on shaft 6 and is secured to a sprocket wheel 13 that is similarly n iounted on said shaft. A pair of pawls 14 is attached to ratchet 12 and is PUMILMOTOR. J FRANK AN; t held in engagement with the teeth of a ratchet 15 by means of springs 16 borne by rin 17 fastened to ratchet 12, said ratchet 15 ein secured to drum 5 so that, when the rope 4 causes drum 5 to rotate, ratchet 15 rotates with said drum and causes` ratchet 12, sprocket 13, and shaft G to rotate therewith. A pawl 18 is pivoted at 19 to bracket 11 so that both ends of said pawl alternately engage the teeth of ratchet 12. The teeth of said ratchet 12 point in the opposite direction to that in which the teeth of ratchet 15 point, and when drum 5 is rotated by the pull of rope 4 in the manner hereinabove described, pawl 18 allows Iratchet 12, sprocket 13, and shaft 6 to rotate therewith, but, while said drum is being ro tated in the opposite direction to wind said rope thereon, pawl 18 prevents ratchet 12, sprocket 13, and shaft G from rotating backward, with the result that the teeth of ratchet 15 ride past pawls 14. Q Sprocket 13 drives an endless chain 20,

i that travels in engagement with a sprocket wheel 21 and a tlanged pulley 22, said puley being journaled in a weight 23. S roc 121 is fastened to a sector-toothed w eel 24 and is loosely mounted on pintle 25 secured the casing of pump 1. Said lever is pivoted at to a bracket 31 attached to the casing of said pump and is provided with a shoulder 32. Said shoulder normally engages a pin 33 borne by wheel 24 and, when sprocket 13 drives chain 20, said shoulder prevents wheel 24 and sprocket 21 from rotating, with the result that said chain raises weight. 211, thereby causing rod 26 to move upwardly through slot 2T in lever 28 and, also, caus- 2 ing the upper part of chain 20 that extends between sprockets 13 and 21 to become slack. A collar 34 that is fastened to rod 2G by i means of a set-screw 35 or the like moves upwardly with said rod and raises the end o lever 28, whereby shoulder 32 moves away from pin 33 and leaves wheel 24 and sprocket 21 free to rotate on pintle 25. l 7hen pin 33 is-released in the manner just.

described, weight 23 descends rapidly and causes chain 20 to rotate sprocket 21 and wheel 24. As weight 23 moves downwardly rod 26 travels with it and moves collar 31 away from lever 28, thereby allowing lever 28 to descend, with the resultl that. shoulder 32 engages pin 33 after wheel 24 and s n 'ocket 21 make a complete revolution. t aid sprocket 21 and wheel 24 are thus irevented from rotating farther until weight l a slieave 43 pivoted at 44 to the casing of A rack frame 36 is arranged to be op-l pipe 55 and is .56 that carries t e erated by means of the sector-toothed wheel 24 and is provided internally with two rows of teeth 37 and 38, the teeth 37 being located opposite teeth 38. Said rack frame is guided in its movement hy means of a pair of flanged rollers 39 that is ivoted to brackets 40, respectively, fastene to the casing of p ump 1, one roller 39 being adjacent one side of frame 36 and the other roller being' adjacent the other side of said frame. A` flexible member 41 is fastened to an arm 42 borne by rack frame 36, and passes over pump 1. A weight 45 is attached to'the end of member 41 in order to hold said menii tidn tiled of even date. i vice is connected to carbureter 3 by means of chine,

her in tension so that. rack frame 36 is held l gnormally in position to cause teeth 37 to? partly mesh with an end tooth of wheel 24, with the res'ult that the other end tooth of said wheel is normally out. of engagement Said measuring derovided with a drain pipe overlow of hydrocarbon oil in said device back tothe source of oilI supply. A pipe 57 leads from carbureter 3 to lighting or heating apparatus (not 'y shown), and is provided with a controlling valve 58.

While this invention is particularly adapted to be used to operate a pump for forcing hydrocarbon oil to a carbureter of a gas niayet it should be understod that same can be utilized to operate a pump for other purposes, for example, pumping air, gases, or other liquids. I

The operation of the apparatus is as follows: As the ull of weight 10 on the rope 4 causes sprocket 13 and shaft .6 to rotate in the manner hereinabove described, pump 1 compresses the air in the usual manner and forces same through pipe 2 to carbureter 3.

Said sprocket rotates comparatively slow ,with teeth 38. When wheel 24 makes'a comnd'dlves Chain 20 which falSS Welght 23 plete revolution in the maner hereinabovey Until con 34 engages .and .Mts the -end described, the teeth thereof move in engagei of lever 28, thereb releasing pin 33. Weight ment with the teeth 37- duringl part of the i 23 then drops su denly and causes chain 2O *,"emlution, thereby causing rack frame 361i tto rotate sprocket 21 and sector-toothed Rod 26 moves lo move upward] and to carry with it. teeth 38. Tho teeth o said wheel then move out of engagement with the teeth 37 and into engagement with teeth 38, and, during thc remainder of the revolution of said wheel, the teeth thereof move in engagement with teeth 38, with the. result that rack frame 36 moves downwardly to its normal. position, i. c., teeth 38 disenga e the teeth of wheel 24, and teeth 37 iarty mesh with an end tooth of said wheel.

A piston-rod 46 is secured in any suitable manor to rack frame 36 and is arranged toactuate piston 47 of a ump 48, said pum being connected to a tee 9 or the like. Eac i revo iition of wheel 24 causes rack frame 36 to make a recprocation, with the result that piston-rod 46 moves with said rack frame and causes piston 47 to make a suction f and a discharge stroke. is attached to one end of tee 49 and is l connected to a pipe 51 that leads to a reser- A check-valve 50 voir or other receptacle (not shown in the drawings) containing a hydrocarbon oil, said va ve being adapted to open during the suction stroke of piston 47 and to close during the discharge stroke of said piston. A check-valve 52 is fastened to the other end of tec 49 and is arranged to close during the f suction stroke of piston 47 and to open during the discharge stroke of said piston. A pipe 53 is connected to check-valve 52 in order to convey the hydrocarbon oil to a measuring device 54 that is preferably eoni `jitructcd like the measuring device constituting the subject-matter of my other applicawheel 24 to rotate rapidly. l downwardly with weight. 23 with the result that collar 34. moves away from lever 28,

engage pin 33 after wheel 24 makes a conidevice 54. Said measurin a predetermined amount o hydrocarbon oil through pipe 55 to earbiireter 3 and dis- 1 charges any superfluous oil back through pipe 56 to the source of supply. The air combines with the vapors of the hydrocarbustible e 57 to lig thereby causing shoulder 32 of said lever lo plete revolution. Said wheel is thus ire.-

vented from further rotation until weight 23 is again raised and pin 33 is released.

i Each revolution of wheel 24 reciprocates rack frame 36 which actuales piston-rod 46,

whereby said piston-rod causes piston 47 to make a suction and a discharge sli-oke. Duri ing the suction stroke of piston 47, valve 52 closes and valve 50 opens with thc result that a uantit of hydrocarbon is drawn through i va ve 50 into pump 48. The discharge stroke of piston 47 closes valve 50 and opens valve l 52, thereby causing the quantity of oil williin pump 48 to ,flow through valve 52 into pipe 53 that conveys same to the measuring device delivers bon oil within carbiireter 3 and forms a conigas that is delivered through pipe iting or heating apparatus. l Inasmuch as the consumption of the gas tluctuates, the speed at which shaft 6 rotates varies with the rate at which the gas is conl sumed, thereby causing piston 47 to force l hydrocarbon oil to carbiireter 3 only at ini tervals when the pressure in said carburetor reduces sutiiciently to necessitate more air l detent normally preventing the rotation of and oil to be delivered thereto, in order tol maintain the desired mixture of air and the vapors of the oil within said carbureter.; and a weight arranged to hold a rack o This intermittent actuation of iston l17!` said frame in mesh with said wheel when saves a great amount of power t at, obvi-y isame is at rest. ously, would be necessary to actuate a coni 6.
